Abstract

Disclosed is a swimming and surfing board capable of helping a person who even cannot swim to swim freely in water and run on a water surface and propelling itself by using wave energy on a water surface. The swimming and surfing board comprises a board body, butterfly valve flaps, butterfly valve flap mounting hinges, etc. Multiple groups of valve-like devices only allowing one-way communication are formed by means of the described device. When a person treads on the surfing board downwards or backwards, because of the one-way opening and closing structure design of butterfly valves, it is ensured that the surfing board has the maximum resistance when being pushed backwards and the minimum resistance when the leg retracts, so that the surfing board always has a rational force output direction. When the frequency of treading is increased, an output push force is continuously greater than the resistance during continuous reciprocating treading, and when the value reaches a certain amount, a person can move freely on a water surface.

Description

Swimming and wave board

Technical field

The invention relates to a swimming appliance, in particular to a swimming and wave board that can help people swim at high speed in the water and run on the surface of the water, and at the same time can use the energy of the waves to move on the surface of the water.

Background technique

The density of water is about 800 times that of air, and its specific gravity is lighter than that of the human body. Therefore, people will have a lot of resistance when moving in the water, but will sink when they are still. At present, people learn to swim with a longer In the course of time, you can move freely in the water if you can’t get into the water; using a life jacket or a lifebuoy, you can not sink in the water, but it is basically not helpful for learning to swim and moving freely in the water, but it hinders people. Exercise; using long-distance approach, the human long jump world record is about 9 meters; the long jump without a run-up, the distance is less than 5 meters; and without the help of people in the water, the exercise efficiency is much lower than that on land . Using surfboards, people can achieve a higher speed in the water, but surfing requires certain wave height conditions. It is basically impossible to use surfboards for long-distance traffic on the water; in order to help improve people's movement in the water Speed, people invented fins, but fins have the following obvious weaknesses: 1. The fins are an extension of the human foot, and the output thrust is from the heel to the toe. This output force is asymmetrical to the human foot, so It is very easy to cause the movement of the human foot; 2 because of the asymmetrical combination with the human foot, it basically relies on the human leg to kick the water to move; 3. The fins made of rubber or plastic materials must have a certain degree of flexibility. In order to be able to have an ideal force output when kicking the feet; simply put, the current fins are suitable for freestyle, backstroke, and butterfly, while the most labor-saving breaststroke is not suitable for fins. This is Because the fins with the ankle as the node increase the asymmetry of the foot, it is very easy to cause fatigue and damage to the foot muscles; if you use the breaststroke backward kicking action, the flexible structure and the fins that are asymmetrical to the foot will occur Deformation, unable to obtain the ideal force output.

Summary of the invention

The purpose of the present invention is to try to overcome the various shortcomings mentioned above by adopting a new and simple swimming and wave board device, so that even people who can’t swim can move freely in the water and on the surface immediately after entering the water. .

We know that the so-called inability to swim is the inability to keep the body (extremities) in the water in a correct movement and static posture. Once you can freely maintain a correct movement and static posture, you can be said to be able to swim. Water has resistance and buoyancy. As mentioned above, using long-distance run-ups, the limit distance for humans to jump on land is about 9 meters; long jumps without run-ups can reach a distance of less than 5 meters; and people are in the water. Without borrowing, the efficiency of movement is much lower than that on land. However, a normal person, without a run-up, pedaling hard on the wall of the swimming pool, can easily move more than ten meters with the help of the buoyancy of the water on the body. The present invention borrows this principle to design a swimming and wave walking board to form a moving wall behind the user's feet, so that the swimmer can exercise at high speed and effortlessly for long distances. This kind of swimming and wave board can also step on the top of the wave when the waves are small and the surfboard cannot be used, and use fast-moving waves to promote people's movement on the water; because this kind of swimming and wave board can Let people run on the surface of the water. If they run on the top of the wave (or tread the wave), they can be pushed forward by the wave. In addition, this kind of wave board cooperates with the help of corresponding light parafoil device or sail device and towing rope, and at the same time, it can realize the high-speed movement or take-off of single or multiple people on the water surface by borrowing the abundant wind on the sea. Many people fly people into the sky with the help of towing ropes. The principle is just like we are used to flying kites.

The purpose of the present invention is achieved as follows:

A swimming and wave treading board, consisting of a plate body and reinforcing ribs, asymmetric one-way butterfly valve disc, or gate-type one-way valve disc, asymmetric one-way valve closing limit point, asymmetric one-way valve opening limit point, single Toe valve pivot, toe guard plate, lace hole, drainage hole, vertical positioning plate, vertical positioning belt perforation, connecting bolt, vertical lace, etc.; among them, in the center of the wave treadle, there is a place where a person’s foot rests. There are lace holes and drainage holes; a vertical positioning plate is installed behind the human foot position, and the vertical positioning plate is vertically connected to the swimming and wave board body by connecting bolts; a vertical positioning plate is provided on the upper part of the vertical positioning plate. With perforation and vertical tie, the calf is fastened to the vertical positioning plate through the perforation; around the position of the human foot and the vertical positioning plate, the front and back and left and right are respectively symmetrical and parallel to the foot. Multiple groups of rectangular check valves can be freely combined , The multiple groups of rectangular check valves are combined check valves; the asymmetric check butterfly valve plate is placed in the check valve shaft through the check valve shaft, and the check valve shaft Above, set a one-way valve opening limit point, and on the side of the one-way valve, set a one-way valve closing limit point.

Further, the combined one-way valve of the swimming and wave treading board is arranged vertically with the foot, and the asymmetric one-way butterfly valve disc or gate-type one-way valve disc is placed in the one-way valve shaft through the one-way valve shaft, Above the valve pivot, set a one-way valve opening limit point, on the side of the one-way valve, set a one-way valve closing limit point, the asymmetric one-way butterfly valve is placed in the one-way valve pivot, The small butterfly valve body is at the front and the large butterfly valve body is at the back.

Optionally, the combined check valve of the swimming and wave treading board is arranged vertically with the foot, and the asymmetric check butterfly valve plate or gate type check valve plate is installed in the check valve shaft through the check valve shaft, and the check valve is placed in the check valve shaft. Above the valve pivot, set a one-way valve opening limit point, on the side of the one-way valve, set a one-way valve closing limit point, the asymmetric one-way butterfly valve is placed in the one-way valve pivot, The large butterfly valve body is in the front and the small butterfly valve body is in the back.

The swimming and wave treading board of the present invention is composed of a plate body, a butterfly valve disc, a butterfly valve disc mounting pivot, a butterfly valve disc closing limit stop, a butterfly valve disc opening limit stop, a wave stepping board toe guard board, tether perforation, and foot pedal drainage hole , Vertical fixing plate, vertical fixing belt perforation, connecting bolts, vertical fixing belt, etc. The main technical characteristics of this kind of swimming and wave treading board are: it is a rectangular shape, the position of the human foot is in the center of the wave treading board, around the position of the human foot, several groups of rectangular one-way are arranged symmetrically in front and back and left and right. Drainage holes, the number of one-way drainage holes can be determined according to the specific use function. When the performance requirements are simple (such as focusing on swimming), it can be less set; when it is required to have better wave riding and water skiing functions, it can be appropriate Of multiple settings. At the appropriate positions at both ends of the drain hole, a pair of butterfly valve pivots for fixing the asymmetric one-way butterfly valve discs are arranged. The butterfly valve pivot is composed of high-strength and high wear-resistant materials. A butterfly valve opening limit stop is set on the upper side of the butterfly valve pivot. The function of this limit gear is to ensure that the butterfly valve can only be opened to a certain position. On the side of the drain hole, set a butterfly valve to close the limit gear. The function of this limit gear is to ensure that the butterfly valve can only be closed to a certain position. Fix the asymmetric one-way butterfly valve in the butterfly valve pivot in the drain hole. When a person steps on the wave treadle downwards or backwards, because of the one-way opening and closing structure design of this butterfly valve, the asymmetric one-way butterfly valve is this When the time is closed, the entire swimming and wave board are in a closed state, and the resistance is the largest, so the pedaling force issued by the operator at this time can obtain a maximum reaction force. When the swimmer’s foot pedals to the maximum extent, the wave treadle becomes the resistance of the movement. At this time, the butterfly valve plate will automatically open under the action of external force until the butterfly valve plate touches the butterfly valve closing limit stop. At this time, the wave treadle The resistance is minimal. The operator's legs retract back, and at this time the butterfly valve of the wave treadle continues to open, and the wave treadle will continue to be in a state of least resistance. Generally speaking, according to different performance requirements, the number of one-way valve combinations will be different, so the area of the one-way butterfly valve is about 30% to 70% of the total area of the wave tread. Here we take a 50% The median value. In this way, in each reciprocating step, we output 60kg of force when pedaling (this value is not large, as long as a person jumps off the ground, the force emitted is greater than his weight). At this time, we pass the foot posture The control of the wave treadle makes the wave treadle in the state of maximum resistance. This pedaling force can obtain approximately 100% of the reaction force; when the legs are contracted, the one-way butterfly valve opens, and the wave treadle has a theoretical 50% resistance at this time. When running, because the wave treadle is submerged into the water surface very shallowly, once it leaves the water surface, the resistance during contraction will be greatly reduced. In the state of breaststroke in the water, the knee joint is the center of the circle. Through the control of the knee joint and the foot joint, the wave board is approximately perpendicular to the human body when pedaling, and is in the state of maximum resistance, thereby obtaining the most ideal forward power; When the foot is retracted, the angle between the foot and the calf is controlled, and the butterfly valve is already in the open state, so that the resistance of the wave board is at the minimum when it is retracted. Because of the one-way output method of the one-way valve, even if the operator can't swim, as long as the foot can be kept pedaling continuously, the operator can move freely in the water.

Specific embodiment

The purpose of the present invention is achieved as follows: the swimming and wave treading board of the present invention consists of a plate body and a reinforcing rib 1, an asymmetric one-way butterfly valve disc 2 or a gated one-way valve disc 16, a one-way valve closing limit point 6 , One-way valve opening limit point 7, one-way valve pivot 8, toe guard plate 9, lace hole 10, drainage hole 11, vertical positioning plate 12, vertical tie hole 13, connecting bolt 14, vertical tie 15 And other composition. The main technical features of this swimming and wave treading board are: this is a rectangular shape, the position of the human foot is in the center of the wave treading board 1, and a vertical positioning plate 12 is arranged behind the position of the human foot, and the vertical positioning plate 12 is connected by The bolt 14 is vertically connected to the swimming and wave treading board body 1, and the calf is fastened to the vertical positioning board 12 through the vertical tie hole 13 and the vertical tie 15 on the vertical positioning board 12, so as to ensure that the wave treading board and the human body are kept in a correct position. Work angle. Around the position of the human foot and the vertical positioning plate 12, several groups of rectangular one-way valves that can be freely combined are arranged symmetrically, respectively, in the front and the left, and the groups of rectangular one-way valves are combined one-way valves. The one-way valve consists of swimming and wave treading board body 1, asymmetric one-way butterfly valve plate 2 or gate-type one-way valve plate 16, one-way valve closing limit point 6, one-way valve opening limit point 7, one-way valve The number of the one-way valve can be determined according to the specific use function. When the performance requirement is simple (such as focusing on swimming), it can be less set; when it is required to have better wave riding and water skiing functions, It can be set appropriately. At the appropriate positions at both ends of the drain hole of the discharge valve, a pair of one-way valve pivots 8 for fixing the one-way valve discs are arranged. The one-way valve pivots 8 are made of high-strength, high-wear-resistant stainless steel or ceramic materials. A one-way valve opening limit point 7 is set on the upper side of the valve pivot 8. When the asymmetric one-way butterfly valve plate 2 or gate-type one-way valve plate 16 is opened to this position, the angle cannot continue to increase. At this time, the resistance of the wave treadle The smallest. Set a check valve closing limit point 6 at an appropriate position on the side of the drain valve. When the asymmetric check butterfly valve plate 2 or gate check valve plate 16 is closed to this position, the angle cannot continue to increase. The wave board has the greatest resistance. Because of this structure, when a person steps on the wave treadle downwards or backwards, because of this one-way opening structure design, the asymmetric one-way butterfly valve plate 2 and the door-type one-way valve plate 16 are closed, this At this time, the entire swimming and wave board are in a closed state, and the resistance is the greatest. Therefore, the pedaling force issued by the operator at this time can obtain the best reaction force. After pedaling to the maximum angle, the operator’s legs retract back. The symmetrical one-way valve 2 or the gate-type one-way valve plate 16 is opened, and the wave treadle is in a state of least resistance. The setting of the above structure ensures that the wave treadle has a reasonable output direction. Accelerate the frequency of pedaling. In the continuous reciprocating pedaling, the output driving force is continuously greater than the resistance. When this value reaches a certain amount, people can run on the water. When people stand on the top of the wave, do In the above actions, people can move with the waves regardless of the height of the wave.

It can be seen from Figure 3 that when the asymmetrical one-way butterfly valve plate 2 is in a fully opened state, it is not perpendicular to the swimming and wave treading board 1, so that the reliable action response when it is closed can be ensured, because it is attached In the state of Figure 3, if the asymmetric check valve 2 is completely perpendicular to the wave tread plate 1 (see Figure 4), if the pedaling force of the operator is perpendicular to it, the asymmetric check valve 2 may not act, so When the asymmetrical one-way butterfly valve plate 2 is in a fully opened state, it is not perpendicular to the swimming and wave treading board 1, which can prevent the one-way valve from not operating.

Fig. 4 is a detailed structure diagram of the asymmetric one-way butterfly valve disc 2. In actual use, the one-way valve shaft 3 is placed in the one-way valve shaft 8, and the large butterfly valve body 4 and the small butterfly valve body 5 are located on the one-way valve shaft 3. This design has the following advantages: because the large butterfly valve body 4 and the small butterfly valve body 5 are located on both sides of the one-way valve shaft 3, the forces of the two valve bodies are opposite, because the large and small valves Due to the difference in body area, the force of the large butterfly valve body is always greater than that of the small butterfly valve body, so the opening and closing of the asymmetric one-way butterfly valve plate 2 is determined by the force direction of the large butterfly valve body 4; increase the strength of the asymmetric one-way valve 2; The large and small surface design can shorten the conversion distance and speed of the asymmetric check valve 2 from open to closed (the conversion distance is the width of the large disc valve body);

Figures 2 and 3 are parts of the open and closed state diagrams of the asymmetrical one-way butterfly valve plate 2 of the right foot of the swimming and wave treading board. Fig. 6 and Fig. 7 are parts of the opening and closing state diagrams of the asymmetrical one-way butterfly valve plate 2 of the left foot of the swimming and wave treading board.

Fig. 8 is a part of the closed state diagram when the door check valve is used for the swimming and wave treadle; Fig. 9 is a part of the open state diagram when the door check valve is used; Fig. 10 is the door butterfly valve plate 16 When the gate-type butterfly valve plate 16 is used, the one-way valve opening limit point 7 is below the gate-type butterfly valve plate 16, and its working principle is the same as the one-way valve composed of the asymmetric one-way butterfly valve plate 2 described above.

The one-way valve plate of the swimming and wave treading board adopts two setting modes: a parallel arrangement with the foot and a vertical arrangement. Figure 1, Figure 11, Figure 12 show the arrangement state of the one-way valve plate parallel to the foot, Figure 19 is the top view of the asymmetric one-way valve of the swimming and wave treadmill parallel to the foot. Fig. 13, Fig. 14, Fig. 15, Fig. 16, Fig. 17, Fig. 18 show various working state diagrams when the one-way valve plate and the foot are arranged vertically. Fig. 13 is a side view of the closed state when the asymmetrical check valve is arranged vertically with the foot (the toe first touches the ground when running). Fig. 14 is a side view of the open state when the asymmetric one-way valve is arranged vertically with the foot (toe touches the ground first). Figure 15 is a side view of the closed state when the asymmetric one-way valve is arranged vertically with the foot (the heel first touches the ground when running). Figure 16 is a side view of the asymmetric one-way valve in an open state when the asymmetric one-way valve is arranged vertically with the foot (heel touches the ground first). Figure 17 is a gliding swimming and wave board (with asymmetrical one-way butterfly valve). Figure 18 is a gliding swimming and wave board (with gate butterfly valve).

The butterfly valve plate of the swimming and wave board is divided into two types: asymmetric one-way butterfly valve plate 2 and gate type butterfly valve plate 16. Among them, the asymmetric one-way butterfly valve plate 2 is divided into large butterfly valve body 4, small butterfly valve body 5, The dislocation arrangement is the same as the planar arrangement in Fig. 5. The asymmetrical one-way butterfly valve disc 2 and the gate-type butterfly valve disc 16 in a planar arrangement are suitable for use in the state of Fig. 17 and Fig. 18. At this time, the asymmetric one-way butterfly valve disc 2 and the gate-type butterfly valve disc 16 are perpendicular to the feet It is arranged and is a relatively flat surface. The design of this structure can ensure that the one-way valve is automatically closed when glide on the water surface, so that the resistance of the wave treadle is minimized when it glides on the waves.

Figure 19 is a top view of the right foot when the swimming and wave treadle check valve is arranged in parallel with the foot. Figure 20 is a partial top view of the swimming and wave treading check valve. The wave board with this layout is suitable for swimming and running on the water.

The layout of the small butterfly valve body 5 in the front and the large butterfly valve body 4 in the figure, and the use of the asymmetric one-way butterfly valve plate 2 shown in FIG. 5 will make the swimming and wave pedals of this configuration better Surfing ability.

The above-mentioned drawings are schematic diagrams. The specific one-way valve needs to be combined on the swimming and wave board, which can be flexibly controlled according to the different use requirements of the wave board.
